Cette étude met en évidence les facteurs clés affectant le calendrier du stockage définitif des déchets radioactifs de haute activité. Elle analyse comment l'acceptation sociale, la robustesse technique, la prise en compte des aspects environnementaux et la faisabilité économique...

Les isotopes radioactifs et stables sont utilisés à travers le monde dans de nombreux secteurs, notamment en médecine, dans l'industrie, l'agriculture et la recherche. Les isotopes sont irremplaçables dans bon nombre de leurs applications et s'avèrent généralement plus efficaces et moins...

Energy and nuclear policy makers face many challenges as they evaluate options to ensure an adequate supply of electricity while pursuing environmental, economic and energy security goals. Many analysts suggest that nuclear’s share of global energy supply could decrease in coming decades. If...

Understanding the accident at the Fukushima Daiichi Nuclear Power Plant is important for safe and timely decommissioning of the reactors. This objective, together with the development of better computer codes for analysis of severe accidents, was the aim of the benchmark study conducted under...

Experimental facilities in nuclear energy are key to addressing safety issues. The recent loss of some critical infrastructure, from facilities to industry expertise, has therefore become a concern for many countries. In response, the NEA has launched several efforts to address the matter as...

The existing nuclear fleet remains the largest low-carbon source of electricity generation in OECD countries. In 2021 the average nuclear power plant had already been operating for 31 years and some 30% of reactors worldwide were already operating under long-term operation conditions. The...

The main objective of national energy policies in OECD countries is to ensure the availability of secure and economic supplies with minimal environmental impact. This publication addresses the roles and responsibilities of governments in the field of nuclear energy, within the context of broad...

A key challenge in the development of safety cases for the deep geological disposal of radioactive waste is handling the long time frame over which the radioactive waste remains hazardous. The intrinsic hazard of the waste decreases with time, but some hazard remains for extremely long periods....

This technical report describes the results of the Nuclear Energy Agency's CLAYTRAC project, in which natural tracer data from nine sites was evaluated to assess potential impacts of disposal of radiological waste in geological repositories. It shows scientific information from numerous sites...
